500 Festival Open Invitation

The 500 Festival Open Invitation was a professional golf tournament on the PGA Tour, played during the 1960s in Indianapolis, Indiana. It was sponsored by The 500 Festival, a not-for-profit volunteer organization created in 1957 to organize civic events to promote the Indianapolis 500.

The tournament was played at the Speedway Golf Course, located in the Indianapolis Motor Speedway complex; the exception was in 1965, when it was played at Greentree Country Club while the Speedway was undergoing renovations.
